  • Electrostatic air filter
    Patent number: 8721775
    Abstract: The electronic air filter has a pair of pads between which a grid is sandwiched. The pads are composed of glass fiber or like filtering medium while the grid is composed of two or more pads of carbon interconnected by a network of filaments having a cotton core surrounded by a graphite sheath. The grid is connected to a source of electrical power at a voltage at which a corona field develops around the grid with resulting polarization of the grid.
